The High Efficiency Drilling Technology In Weizhou Field Of Beibu Gulf

The Weizhou field of Beibu gulf has contained abundant oil and natural gas .Despite the oil company had done lots of explore and built many product rigs ,Still many field not be researched .because of the broken formation configuration and in some fields ,Some formation has been lack of. So, we still need do many job to find the oil.During those years , With the development of technology of drilling job .The high efficiency drilling technology in Beibu gulf also being more and more maturity .But because of some knowledge still not completely .So, during the drilling project ,we still met some accidents of the well. So This article aims at analyzing in detail the geographical features of the strata in Weizhou Field of the northern gulf. According to the on-the-spot operating situations, the data will be respectively analyzed and optimized within different structure of different well depth. Considering the features of the pay zone rocks, the author has established the sensitivity test of the oil pay zone and produced the evaluation, so as to put forward an ideal mud weight standard and pH value as well as other requirements related to the performance. Since the mud rock in the second section of Wei Field is easy to slake and collapse, the author successfully put forward a mud system with strong plugging ability.Furthermore, in order to solve the following problems which exist in the ocean drilling, such as the high risks, high cost, the dense distribution of the rig platform, short well distance, difficulties in building and holding angle, the author bring forward Rotating Guiding Assembly, which could solve the fieldwork problems.I believe throughout the test job and practice of this field . The conclusion will give the directional ideas .So in the coming days , They can make the right choice to avoid the accidents during drilling projects and achieved high efficiency drilling jobs.
