长沙岭构造带三维地层压力计算方法及分布规律
Calculation method and distribution of three-dimensional pore pressure in Changshaling Structural Belt
摘要
Abstract
Changshaling Structural Belt is an important oil and gas exploration area in Jiudong Basin, and abnormal high pressure is universal in the zone. The paper proposes a new three-dimensional (3D)pore pressure calculation method based on single point hypothesis, which can use 3D interval velocity data to estimate 3D pore pressure. The novel method was applied to the 3D pore pressure calculation and analysis of Changshaling Structural Belt. Firstly, the pore pressure profile and model parameters of several key explor-atory wells were established. Secondly, the 3D interval velocity data of the structural belt was obtained by seismic inversion. Further, the computer program was developed, and it was used to calculate the 3D pore pressure of Changshaling Structural Belt. Finally, with the 3D pressure results of Changshaling Structural Belt, the pore pressure distribution of this zone was systematically analyzed, with positive results.关键词
