The specific embodiment:
Below in conjunction with Fig. 1 ~ Fig. 7, a preferred embodiment of the invention is described in detail, in order to method characteristic of the present invention and function are described better.
Fig. 1 is that the underground non-cable test system promotes schematic diagram in horizontal well, in figure, related underground non-cable test system is the general term of various downhole testing devices, be not refer in particular to some, its motion initial position is from the end of shaft bottom, the power resources of its motion are in the hook and the rope traction that promote drilling rod, and the hoisting velocity of hook is determined by the rotating speed of ground wire rope drum.Be explanation shown in figure as an example of horizontal well example, it vertically creeps into distance

t(n).
Fig. 4 installs the speed probe resolution chart, as shown in the figure, speed probe is arranged on the trundle (diameter is D) that constantly contacts with wire rope, trundle is fixed on the pedestal of faking device, when wire rope moves, drive trundle rotation by frictional force, the rotating speed that speed probe records trundle is data over time, and the definition drum rotation speed time series data of surveying is the rotating speed array
W(n) and corresponding time array
t(n).
Fig. 5 is effective lifting time period schematic diagram of judgement underground non-cable test system, and in figure, abscissa represents the time
t, ordinate represents corresponding hook load
N, curve has reflected every section interior duty of time of hook, has also reflected underground non-cable test alliance Changing Pattern situation, its each interval expressed concrete meaning is explained as follows:
0 ~ t1 represents the hook process that hoists constantly, and this moment, cylinder started, and drives drilling rod and moves upward, and the underground non-cable test system also follows and hoists, this moment hook load almost continous-stable at a certain specific non-zero peak value, so this section period be effectively to promote the time period;
T1 ~ t2 represents to transfer hook on drilling rod constantly, hook also may participate in other work or be in waiting process this moment, the load of this process can be less than the hoist load of drilling rod process of front and back, and this working time is not to be the underground non-cable test systematic procedure that hoists, and is not therefore effectively to promote the time period;
In like manner: t2 ~ t3 constantly, t4 ~ t5 constantly and t6 ~ t7 effectively promote the time period, and t3 ~ t4 constantly, t5 ~ t6 moment is not effectively to promote the time period.
In sum, judge whether the underground non-cable test system really be raised effective time section foundation be hook load
N(n) whether there is continous-stable non-zero peak value, and also continous-stable of roller rotating speed, specific algorithm is achieved as follows:
1) scanning hook load sequence
N(n), n is total number from 1 to Num(Num), when
N(
n+1)=
N(
n)+e and
N(
n) the 0(fluctuating error scope of e for allowing wherein, can be set as 1%
N(n) in the time of size), record the numerical value of n with array m (s), namely m (s)=n(wherein s automatically increase since 1).
2) scan time series
t(n), n is total number from 1 to Num(Num), when n=m (s), use array
t '(m) record
t(n) data, namely
t '(m)=
t(n), at this moment
t '(m) segment data effective time that really is raised for the underground non-cable test system.
Fig. 6 is effective range of lift schematic diagram of judgement underground non-cable test system.The effective lifting time array definite according to above-mentioned principle
t '(m), in like manner obtain
W(n) corresponding effectively rotating speed array in
W ' (m), then in conjunction with diameter of cylinder
