Cif2000平台下的核磁共振测井解谱方法研究

介绍了在Cif2000多井解释平台下的核磁共振解谱方法与编程实现。解谱采用加入平滑因子后在特征矩阵的奇异值分解中截去小的非零奇异值的方法，可以在低信噪比时得到稳定的弛豫谱，在油田实际应用中证明了该方法的有效性。根据该方法在Cif2000平台上编制了完整的解谱处理程序，可以直接用于油田的生产实际。

Interaction of free-surface waves with floating flexible strips

The method developed by the author to derive a set of algebaic equations to solve the interaction of free-surface waves with a single floating rigid or flexible two-dimensional platform with small draft is extended to the case that the platform consists of strips with different constant flexural rigidity and mass. The method is based on the application of Green's theorem, with a specific choice of the Green function to arrive at a differential-integral equation along the platform. This equation can be solved exactly by means of superposition of exponential functions, a standard method to solve a set of linear differential equations. After integration with respect to the space coordinate the residue theorem leads to both the dispersion relation along each individual strip and an algebraic equation for the coefficients. Due to very fast convergence with respect to the number of coefficients taken into account the series are truncated. Depending on the water-depth, in each series three to ten terms are taken into account. Results are shown for a structure consisting of several strips that are tightly connected and for disjoint strips. In the latter case the computation of the water level between the strips is also computed. The water level and the reflection and transmission coefficients are not unknowns in the algebraic equation, but are computed afterwards by means of Green's theorem.

自升式平台深水化改造的新模式及其可行性分析

针对我国现有自升式平台存在的不能满足深水域勘探开发的要求以及造价过高等问题,提出一种自升式平台深水化改造新模式——分体坐底自升式平台,在基本不改变原有平台结构的基础上,通过增加可沉浮平台下体,使作业水深增加50m以上,而造价比同工作水深的常规自升式平台低得多。文章介绍了该分体坐底自升式平台的结构方案、作业工况及操作程序,分析了该平台的技术可行性和经济可行性,并提出了深入研究和具体实施需要解决的问题。
