普光气田是中国石油化工集团公司重要的油气勘探战略接替区。该地区由于地质构造复杂,地层倾角大,地层自然造斜能力强,严重制约了该地区勘探目的的顺利实现。为了在普光气田P103-2井施工中充分利用地层自然造斜规律,在普光气田地层自然造斜规律研究的基础上,对P103-2井的钻井施工方案(如造斜点、井身剖面、钻井参数等)进行了精心优化设计。现场实钻结果表明:P103-2井根据实钻的井身轨迹合理调整造斜点、井身剖面和钻井参数,充分利用地层的自然造斜特性,尽量减少定向或扭方位等工作,从而达到了提高钻井速度的目的。
Puguang Gas Field is an important oil and gas exploration strategy succession zone of China Petrochemical Corporation. Due to the complicated geological structure, large dip angle of stratum and strong ability of natural strata formation, the success of exploration in this area has been severely restricted. In order to make full use of natural stratification regularity in the construction of P103-2 well in Puguang Gas Field, based on the study of natural formation regularity in Puguang Gas Field, the drilling program of P103-2 well, Drilling parameters, etc.) were carefully optimized design. The results of on-site drilling show that P103-2 well adjusts the formation point, well bore profile and drilling parameters according to the wellbore trajectory of actual drilling, and makes full use of natural formation characteristics of strata to minimize the work such as orientation or torsional orientation so as to achieve The purpose of improving drilling speed.
