Comprehensive Factors To Go Down The Net Density Calculation Method

In this paper, a combination of factors influence go down the method of calculating density, comprehensive and thorough analysis of the factors affecting the well density, the basic three categories, geological factors, the development of technology factors, economic factors, and explained how they affect well density, and the importance of points according to their influence of the two types of primary and secondary factors.Focus on the well density calculation, with a starting pressure gradient method to calculate the density of the Technical Limit Well, innovation and the introduction of the two calculations starting pressure gradient formula to calculate the new method, that is the scene of the production of dynamic data method, rheology theory method.In research techniques reasonably well pattern density calculation method, an innovation established in line with the scene heterogeneous reservoir, practical considerations influencing factors is extremely comprehensive and careful a calculation formula of the ultimate recovery model, that is completely amendments to improve the xi e formula of this thesis is to improve after xi e formula than in all previous literature correction model is superior, extremely comprehensive.Elaborated on the iterative method of calculation of economic and Ultimate Well density curve of the intersection of law, describes the detailed steps to take advantage of this method to calculate the economic optimum density value and economic Ultimate Well.The biggest innovation is created to meet the technical development effect the best and the best economic benefits and is suitable for the vertical well, horizontal well muti-well type of well density optimization model, it is almost the most accurate among the various calculation methods,the best method of calculation well density, the only fly in the ointment is that it still requires manual processing is based on the parameters used in the xi e formula evolved from the development of theoretical basis, the calculation process will be outside (experimental equipment, etc.) as well as human factors and errors.Methods of mathematical statistics, the cumulative oil production and production time, oil production and production time, the relationship between the total number of wells and production time, to overcome the deficiencies of the experimental methods based on xi e formula place, the methods used in the calculation process parameters directly from the site, and does not require manual handling is not affected by the outside world (laboratory equipment) and the influence of human factors and errors, so its results can truly reflect objective out the actual situation of the oil field, some drawbacks that they can not meet the technical development effect of the best and economic benefits of the best, only a simple calculation of the economic well network density.From the perspective of the oil field penetration and development stage all the different scope of application, different advantages and disadvantages of technology and economic well density calculation method detailed classification.Zhao concave H3, â…£31reservoirs. An peng H3IV21-3reservoir three reservoirs and Shang he oilfield to â…¥ oil group as an example, full of its regional profiles, geological features, reservoir and fluid properties, and development status, the current well web presence combined with the well pattern density calculation method in this article, combines the advantages and disadvantages of calculations and a variety of methods, scope of recommended Zhaowa H3, â…£,31reservoirs using reasonable technical xi e equation method well spacing density S=18.37port/km2, it is recommended that the security shed H3, â…£,21-3reservoir and Shang he Oilfield VI oil group to adopt reasonable well density of the reasonable oil production rate method to calculate the amount of technology, namely of An peng H3IV21-3reservoir Technical reasonable well density S=14.46port/km2in Shang he Oilfield VI oil group technology reasonably well network density S=19.1port/km2; recommended Zhao concave H3, â…£,31reservoirs economic well density value using the net present value of economic dynamics result of the calculation method, the security shed H3, â…£,21-3reservoir to adopt mixed well type of vertical wells and horizontal wells to optimize the results of the model method, and the proposed Shang he Oilfield VI oil group the results calculated by mathematical statistics.
