摘要： An energetic charge for propellant fracturing may include a propellant material or a shape of the energetic charge being selected such that a rise time of a deflagration of the energetic charge is determined to be in the propellant fracturing regime. The propellant fracturing regime may be defined by a set of linear equations associated with the rise time for pressure from the deflagration of the energetic charge. The rise time may be calculated based on an equation ε = (dP / dt) / E, where ε represents a strain rate, dP/dt represents a change in pressure with respect to time, and E is Youngs modulus, and where the set of linear equations relate the rise time to a borehole diameter.

摘要：一种可控震源分区同时扫描激发方法，采用以下步骤实现：1）将工区划分为A区、B区，A区位于工区两侧靠近边界的位置,B区位于工区的中部；所述的A区有两个区块，按顺序分为A1区、A2区；2）按炮点分区调整激发顺序；计算在Ready信号队列中每两个炮点之间的距离，距离大于最小同时激发距离的为满足同时扫描激发条件的炮点；如果同时扫描激发条件的炮点分别位于A1和A2区，不进行激发，其它区进行激发；在Ready信号队列中位于B区的炮点进行滑动扫描或者交替扫描，当Reday信号队列中位于B区的炮点有多个，要计算炮点距离工区中点的距离，距离小的优先执行滑动扫描或者交替扫描。使用上述方法进行激发可以有效地提高作业效率。

摘要： Methods and apparatuses for acquiring marine seismic data to generate images or determine properties of an interior section of the Earth using simultaneous sources. The time required to acquire a seismic survey is decreased by increasing the speed of the source towing vessel (or decreasing the data sampling density, or increased sampling interval) using multiple simultaneous sources. After separation with simultaneous source technique and combination of separated datasets, seismic data with designed data sampling density or better are acquired.

摘要： A single critically damped acoustic stack yields a wide frequency range as an acoustic transmitter or as an acoustic transducer having particular use in well integrity determination. The critically damped present acoustic stack utilizes a plurality of stacked acoustic elements such as piezoelectric ceramics that are energized in two manners, providing different center frequencies, each producing a respective center frequency of 100% bandwidth to yield an acoustic stack having a total bandwidth exceeding the bandwidth of an acoustic element or the bandwidth of the plurality of acoustic elements. One manner of energizing is to pulse only one of the the acoustic elements. The other manner is to pulse a first acoustic element then pulse a second acoustic element after a delay equal to the amount of time it takes for the first pulse to reach the face of the second acoustic element. The acoustic elements are bonded together and onto a critically damped backing of tungsten, The assembly is retained in a housing that is preferably made of PEEK. The acoustic stack is primarily used in pulse-echo analysis of metal casing wall thickness and cement bond quality detection of wells.

摘要： A technique is designed for conducting a seismic survey. The technique utilizes a plurality of vibrator arrays employed to conduct a seismic survey utilizing low frequency and high frequency vibrators in each vibrator array. The plurality of vibrator arrays continuously sweeps low frequency signals via low frequency vibrators. While sweeping low frequency signals, high-frequency vibrators emit high-frequency signals in an alternating pattern between vibrator arrays to enhance the seismic survey.

摘要： The present invention relates to the vertical seismic profiling (VSP) of geological formations in which the profiling is used to obtain information needed to perform more precise interpretations of geophysical seismic data and to better understand geophysical information. In particular, the disclosure involves using a sound source for generating primary and secondary seismic pulses within well boreholes. Specifically, the seismic profiling system obtains in formation regarding a geological formation traversed by a borehole by one or more controllable downhole seismic pulse generators with drill string tool(s), the tool(s) having contact with and coupled to the formation, a seismic pulsing device a (SPD) is attached to a portion of a drill string such that the pulsing device includes a fluid modulator with an actuator that drives a valve, and a valve controller to control opening and closing the valve thereby causing a high amplitude short duration ultra wide band pressure pulse, generating primary seismic waves sent into the surrounding geological formation and also generating secondary seismic waves. Using one or more geophones, hydrophones or seismic sensing devices for receiving seismic waves is also part of the disclosure. T his device provides a downhole seismic pulse generator that can be used for determining formation information, boundaries, and locations with respect to nearby wellbores, in addition, the device also simultaneously provides for enhancement of the rate of penetration (ROP), measurement while drilling (MWD) directional information, and performing a fracturing while drilling (FWD) function without the loss of drilling time.
