摘　　要：HB构造为上部陆相、下部海相叠置沉积,地质条件复杂,连续地层压力剖面建立困难,这严重影响了工程工艺方案的制定及优化。通过实际应用经验的总结,借鉴前期地层压力预测方法技术,提出了等压趋势线压力预测方法,通过此方法应用有效解决了该区复杂地质环境下的地层压力剖面预测难题,建立了HB构造包括陆相、海相地层在内的连续地层压力剖面,为该区的工程工艺方案的优化设计与施工提供了可靠的基础支撑,为类似复杂地质环境的地层压力剖面预测提供了一种新思路。In sedimentation zone of HB Structure,the upper part is terrestrial formation,the under part is marine strata.In this area,the geologic condition is very complex,it's hard to establish a continuous pressure profile,so the optimization and working out of the engineering plan are impacted.Through summarizing the experience of early time pressure prediction techniques,an equipressure trendline to forecast the marine strata pressure was proposed,the continuous pressure profile of HB Structure form terrestrial formation to marine strata was established.The formation pressure profile prediction technique provided the reliable foundation parameters for this area's engineering design and optimization.The successful application of the methods mentioned in this article provided a new method for the predicting pressure profile in the similar complex strata.
