摘要: 复杂储层条件下,尤其是在薄层、低孔渗、缝洞型等储层的油气勘探与开采是油田进入油气勘探开发后期的研究热点与难点。实践证明,水平井地质导向技术正是解决上述难题的有效手段之一。针对川渝地区复杂的地质对象,从复杂储层地质特点、地质导向难点入手,梳理了现场地质导向作业中常见的问题,并针对性地总结了技术对策,提出了针对此类储层在实际地质导向中要解决好的技术要点。以重庆气矿川东高陡复杂构造带云安XX井为例,综合运用测井、钻井、地质、地震等资料进行钻前设计、地质建模、实时导向,地质与工程紧密结合,提高了储层钻遇率,最终试油产气55×104 m3/d,为该区域产量最高井,现场应用效果明显。

Abstract: With the development of oil field in the late stage of oil and gas exploration and development, more and more complex geological conditions, mining difficulty is increasing, the complex reservoir conditions especially in low porosity and permeability, thin, fractured and cave reservoir of oil and gas exploration and mining is subject to the attention of the educators in Sichuan and Chongqing oil, become a hot and difficult research. Practice has proved that the horizontal well geological guiding technology is an effective means to solve the above problems. This paper aiming at the complex geological objects in Sichuan and Chongqing area, starting from the complex reservoir geological characteristics, geological orientation difficulty, sort out the common problems in the field geological guidance work. The technical countermeasures are summarized in the view of the nature. In order to solve the technical key points of this kind of reservoir in actual geological guidance. Taking Chongqing gas field in East Sichuan steep and complex structure with Yunan XX well as an example, Comprehensive use of logging, drilling, geology, earthquake and other information, Implementate Pre-drilling design, geological modeling, real time guidance, Close combination of Geology and Engineering, Greatly improve the reservoir drilling rate, Final oil production gas up to 55×104 m3/d, it is the highest production wells in the region, the field application effect is obvious.

Key words: the Sichuan and Chongqing Area, horizontal well, geological guidance, reservoir, steep structure
