Comprehensive Geological Research On Dalinghe Reservoir In Jin2-19-8 Block

The description of reservoir is firstly proposed by Schlumberger in the late 1970s, which is based on logging. It takes doghouse dope as the center and reflects the character of the reservoir. The work area which used to be researched is located in southwest of Jin county of Jinzhou municipality in Liaoning province. The area structure's position belongs to the west of the fault depression, the west of the sunken and the south of the slope in Liaohe. The work area is from the well of Jin 2-19-7 in the north to the well of Jin 93 in the south, from Jin 94 in the west to Jin 45-11-20 in the east, it covers about 25000 square meters.The main methods to be adopted as follow:The 3D seismic combining dynamic and static data of fine structure interpret technique, the researching technique of subdivided depositing microfacies and microtectonics, the evaluating technique of multi-well reservoir stratum, which is based on doghouse dopes, the technique of establishing 3D modeling of the reservoir, the technique of second evaluation to the logging, the comprehensive evaluation technique of lateen capacity of oil remaining, the researching technique of geology, reservoir, digital integration to the oil remaining, the technique of description and model building to the fine reservoir, the research of reservoir heterogeneity, the technique of identifying swept layer and quantifying the degree of flooding, the researching technique of the distribution of oil remaining, the certain of the well location of rolling prospecting wells.The outcomes acquired by this passage as follows:discovering and ascertaining 5 new traps, the area of the traps are 1500 square meters. In these traps, there are 3 of them are in favor of becoming reservoir stratum the area is 800 square meters. And 3 rolling wells are also deployed. We also basically know the relationship between rift system and plane distribution in the work area. The relationship between system and plan distribution is mainly ascertained by expounding the fine 3D seismic data of the main oiliness bed of interest. The passage also tells the character and control factor of the reservoir. By researching the precipitation facie, confirming the type and the character of the plan distribution of two kinds of precipitation facie which develop in the special situation of paleogene. The reservoir of Shasan of Daling River is alertly depicted and evaluated.
